WILLIAM P. BROWN, OF ZANESVILLE, OHIO.

Specification forming part of Letters Patent No. 220,463, dated October14, 1879; application filed Aprn 12, 1879.

To all whom it may concern;

Be it known that I, WILLIAM'P. BROWN, ot' Zanesville, in the county ot'Muskingum and State of Ohio, have invented cert-ain new and usefulImprovements inliding andWalking Cultivators; andI- do hereby decla-rethat the followingis afull, clear, and exact description of theinvention, which will enable others skilled in the art to which itapperta'ins. to make and use the same,reference being had to theaccompanying drawings, and to letters of ref-` erence marked thereon,which form a part of this specification.-

Figure l of the vdrawings is a perspective View of my cultivator, andFig. 2. is a perspective detail view of the same.

Identical parts in the drawings are designated by the same letters.

My invention relates to combined riding and walking cultivators 5 and itconsists in devices for raising and lowering the front andA rear ends ofthe cultivator-beams simultaneously and by one movement.

It also consists in the manner of adj ustably attaching` thecultivator-beams to the carriageframe, and also in the manner otattaching and adjusting the guiding-handles when usedl as awalkingcultivator.

A is the carriage, and A is the spindle ot' the axle, and B is thecarriage sub-tongue. The axle is arched upward and attached to thesub-tongue at B. C is a draft frame or bracket, attached to thesub-tongue at Bz'in advance of the axle A, and extending downward aboutlevel with the spindle A. Cl is a brace extending from the axle near thespindle to the bottom portion of the frame C, and provided with aserie's of holes, b, for the purpose of supporting the bracket or frameC at diierent angles or positions.

There is a slot, G2, in the vertical parts of the bracket (l, in whichthe draft-bolt D is inserted, provided with the sleeve D1. 4

E is the frame of the cultivator, to the forward end of which isattached the clevis El, which embraces the sleeves D1, and is retainedin position by means of the set-screw D2. The

'beams E are united by the bolt c and the spreader c1. E2 is theguiding-handle, which is attached by clasp c2 to the extended end of thebolt e.

G is afulcrum or rest for this handle, provided with a slot, g, to whichthe handle is attached by means ot' the bolt g in any desired positionon the curved rest G, thus providii'ig` a shifting or adjustable handle.Instead of this slotted and curved brace G, there may be a curved bar orrod, and an engaging `staple or hook in the handle to attach the parts,

instead of the slot and bolt, as described.

H and H are toggle-levers, connected with the bracketat It L, and withthe draft-bolt D at each end of the sleeve D1, and to each other by thebolt h2, and so constructed that in case these toggle-levers aredeflected from the vertical position they will cause the draft-bolt D tobe raised.

F is a lever fulcrumed to the sub-tongue at f, provided with the handsprin g-pawlf ,which engages with the segment-ratchet F1 in any desiredposition. K is a link attached to the arm F2 of the lever F by means of'hook and eye 7c. The lower end of this lever has a lug, k1, with a hole,k2, in it. K is a hook-bolt for securing the stem ot' the lever K andpermitting it to pass freely through it; or the hook 7c3 of thehook-bolt may be inserted into the hole k2, thus making a rigidattachment of these parts.

L is a rod connecting the lever K and the toggle-levers H, soconstructed that as the lever F is operated, the toggles and lever Kmove in such a manner as to raise and lower the front and rear ends ofthe plow simultaneously and by the one movement.

ln case it is to be used as a walkingcultiva tor, the hook k3 ot' thestaple-bolt kl should not be engaged in the hole k2 of the lever K, bythis means permitting the cultivators to be raised and lowered by thehandle El. In case the hook 7c3 is engaged in the hole k2, the weightot' the carriage and plowman may be utilized in forcing the plow intothe ground.

M is a stirrup engaging the draft-bolt D between the sleeve DI and thebracket G. M is a rack on the stern of the stirrup. N is a lever,provided with a segment-rack, Nl, upon which are teeth for engaging withthe rack M. The longer and fore arm ot' this lever is provided with aseries of holes, in either of' which may be placed the bolt of theconnecting-rod N2, which connects the lever N with the lever F. Thelever N is fulerumed tothe sub-tongue by the bolt n. By means of thislever and its connections, constructed as described, the draft-bolt I)is raised and lowered by the direct vertical motion given to the stirrupM.

The hook and eye I: and the clevis-bolt c3 provide for a horizontalswinging motion for the cultivator, enabling the operator to guide thesame so as to avoid the corn.

The cultivator, as constructed for use, consists of a duplication of theparts above described and represented in the drawings, with theoperators seat situated midway between the handles E2 and lever F.

In case one of the wheels of the carriage drops into a furrow, or uponhigher or lower ground, the operator can at once raise or lower thecultivator to suit, either flexibly or rigidly, as hereinbeforedescribed.

What I claim, and desire to secure by Letters Patent, is-

1. In a riding and walking cultivator, the lever F, provided with thespring-paw] f and arm F2, in combination with the segmentratchet Fl, thelever K, connecting-rod L, toggles II H', and draft-bolt D, as and forthe purposes set forth.

2. The lever K, provided with the lug k1 and hole k2, engaged withthelever F2 by the hookand-eye joint lf, in combination with thehookbolt K', eultivator-beam E, and the connectingrod L, substantially'as and for the purposes set forth.

3. In a riding and walking eultivator, the bracket C, attached to thetongue B and to the axle A by the brace C', and provided with slots U2,in combination with the draftfbolt D, the sleeve D, and the adjustableelevis El, provided with the set-screw D2, substantially as and for thepurposes set forth.

4. In a riding and walking eultivator, the combination of the lever F,the connectingrod N2, the lever N, provided with the segment-gear N, thestirrup M, provided with the rack M', and the draft-bar D, constructedand operating substantially as and for the purposes set forth.

5. Ina riding and walking cultivator, the combination of the lever F,provided with the spring-pawl f' and the arm F2, with the segment-rackFl, lever K, connecting-rod L, toggles H II', and draft-rod D, and theconnecting-rod N2, lever N, provided with the segment-gear N, rack M',and. stirrup M, substantially as and for the purposes set forth.

In testimony that I claim the foregoing as my own I aix my signature inpresence of two witnesses.

WILLIAM I. BROWN.
